The toe-spring section of a cycling shoe plays a key role in supporting efficient pedaling. Too high, and it causes increased tension in the plantar, calf, and hamstring muscles. Too low, and you get a bowlegged, inefficient pedaling form.

Extensive research by Shimano's R&D experts has produced a superior shoe last design with an optimized toe-spring section that promotes a smoother, more energy-efficient upstroke. Built based on feedback from pro riders, Shimano Dynalast helps reduce energy loss on long rides, letting you keep more in the tank for that final sprint to the line.

CUT BRAKING LOSS WITH MORE EFFICIENT PEDALING

Braking loss is the unwanted loss of power that occurs between the crank angles of 200｡ and 360｡ in the backspin direction of a pedal stroke. Shoes incorporating Shimano Dynalast help to reduce braking loss by promoting smoother, more efficient pedaling. If you want to reduce fatigue, get the most out of your legs, and go the extra mile, ride Shimano Dynalast.

PRO-RACING TECHNOLOGY WITHIN YOUR REACH

Shimano’s Custom-Fit technology was designed for Pro Tour racers who demand maximum stability and power transfer, plus the comfort to endure six-hour stages. The heat-molded precision fit and pure anatomical comfort has helped pro racers mount podiums all over the world. They get a competitive edge from 3D upper patterns with glove-like ergonomics. They power up the climbs with retention system rigidity that eliminates gaps, reduces friction, and stabilizes the foot for a single purpose: efficient power transfer. Comfort-Fit is transforming the rides of enthusiasts at every level, because everyone benefits from a perfect-fitting shoe. Optimal precision and power. Pure comfort to go the

Shimano’s Custom-Fit uppers are designed to afford a more comfortable fit during riding. Independent experimental testing *1has shown that reduced friction between the upper and the foot leads to a 13% reduction in the instep temperature compared to nonCustom-Fit

uppers. Less friction, less heat, more comfort.

CUSTOMIZE YOUR FIT WITH OUR HEAT-MOLDABLE INSOLES

Custom-Fit heat-moldable insoles are included with all Custom-Fit-Ready shoe models and they can also be purchased separately. The insoles feature an ergonomic, heat-moldable base with a rigid high-density EVA support structure that provides instant support, comfort, and stability. Whether on the pro tour, at the World Cup, or just around town, Custom-Fit insoles will improve your ride.

A : SNUG-FITTING HEEL CUP

Snug and stable, this newly designed heel cup servesto cradle your heel and keep it reliably in place.

B : MID-LOW ARCH PAD

The first of two modular arch pad options, this one is designed to support an average-to-low arch.

C : HIGH-MID ARCH PAD

Our second modular arch pad option, this one is designed to support an average-to-high arch.

D : HEAT-MOLDABLE TOP LAYER

Allows you to create insoles that fit the unique shape of your feet.

E : HIGH-DENSITY EVA WITH DEEPER HEEL CUP

Provides excellent rigidity, stability, and support

PRESSURE MAP OF CUSTOM-FIT INSOLE

This is the pressure map with or without custom fit innersole. As you can see, red area has the higher pressure. Without custom fit, you can see the high pressure point at the ball girth area, and less arch support can be seen.

After custom fit, the pressure is dispersed evenly, and supported by the broader area. Also body mass movement is less with custom fit innersole. This means the heel bone angle is optimized, and the feet do not move around in the shoes.

TWO ARCH PADS TO SUIT DIFFERENT FOOT SHAPES

Along with the customizable heat-molded insoles, Shimano’s adjustable arch pads bring the perfect shoe fit closer than ever. Depending on your foot curvature, you can choose a high-mid or mid-low arch support pad and enjoy a snug-fitting shoe with optimal pressure distribution.
